Fire-resistant frame structure for a facade or glass roof

Abstract

A fire resistant frame structure for a facade or glass roof, includes a column profile, and a beam profile connectable to the column profile to form a support construction and so positioned relative to the column profile as to form spaces for receiving fire protection glasswork. The column profile and the beam rofile are each made of aluminum and comprised of a supporting core member for receiving static loads, an enclosure surrounding the core member, connecting members joining the core member to the enclosure at formation of a hollow chamber, and adsorbent material received in the hollow chamber and having heat absorbing and hydrophilic properties. The connecting members are formed by bridge members which provide a low heat conductivity to effect a low heat flux from the enclosure to the core member. Thus, crystal water can be released when the adsorbent material is subject to a certain temperature level to thereby cool the metallic framework.
